Title: Real-time digital controller
Inventor: KAWADA SHINYA
IPC: G05B15/02
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To continue stable control by grouping, registering, and storing set constants of a transfer function, which needs to be changed on a halfway, in basic transfer function units, and changing settings by groups in the same timing. SOLUTION: Transfer functions K1 and K2 of control elements 1 and 2 for primary delay corresponding to an RC circuit are represented as K1 =(T /RC)/(1+(T/RC)) ana K2 =1/(1+(T/RC)). In the expressions T is a sampling period. This control system is digitally approximated by backward different approximation, and step response characteristics to this control system are as shown in the figure. Here, when a value C is increased to C' as compared in K1 and K2 , K1 and K2 become K1 ' and K2 ' respectively and registered by the groups in basic transfer function units. Then when a command for set constant alteration is inputted, the time needed for rewriting is secured in the common bus use timing of a management part CPU and then the settings of K1 ' and K2 ' are changed by the groups in the same timing.  Consequently, the deviation of constants after a switching point is eliminated and ideal switching is done.

Title: Image forming device
Inventor: HITSUISHI MITSUHARU
IPC: G03G5/08
Filed: 1995-02-23
Abstract: PURPOSE: To perform a good charging and good image forming by holding a space between a surface to be charged of a photoreceptor drum and a charging surface of a proximity charging member with high accuracy over a long period of time. CONSTITUTION: A step part 103 is formed in a non-image forming region positioned at both sides of a surface to be charged which becomes an image forming region of the photoreceptor drum 104. The step part 103 is formed out of a firm and uniform metallic oxide coating film formed by sol-gel method and then is subjected to a grinding processing. The space between the photoreceptor drum 104 surface and a resistance layer 102 of the charging member 100 is kept at a prescribed value by bringing the step part 103 into contact with the proximity electrifying member 100. Since the step part 103 is solid and is finished with high accuracy by grinding, the space is held with high accuracy when the photoreceptor drum is rotated or used over a long period of time. In such a manner, good charging and good image forming can be attained over a long period of time.

Abstract: PURPOSE:To reduce the generation amount of a waste regeneration liquid, by a method wherein a regeneration liquid having specific acid concn. is passed through an ion exchange tower packed with a strong acidic cation exchange resin from the lower part thereof at a specific flow speed in upward flow and, thereafter, desalted water is injected in said ion exchange tower at the same flow speed as mentioned above. CONSTITUTION:In regenerating a strong acidic cation exchange resin lowered in its ion exchange capacity, a regeneration liquid having acid concn. of 3-8wt.% is passed through an ion exchange tower packed with the resin from the bottom part thereof in upward flow at a flow speed of 2-4m/hr. Subsequently, desalted water is injected in the ion exchange tower from the bottom part thereof in upward flow at the same flow speed as the regeneration liquid of the previous process.
